Slow cooker anchovies may sound unconventional at first, but canned anchovy fillets bring deep savory flavor that melts beautifully into a simple pantry-based sauce. This kind of recipe leans into the old Mediterranean habit of using anchovies as a quiet backbone for a dish rather than a strongly fishy centerpiece, and the slow cooker makes that transformation especially easy. With just five ingredients, it turns a humble tin into a rich, satisfying meal with very little hands-on work.
Serve this over hot pasta, creamy polenta, or thick slices of toasted rustic bread to catch the flavorful sauce. A crisp green salad with lemony dressing or simply steamed green beans make a good contrast to the richness, and if you want to round it out further, a glass of dry white wine or sparkling water with lemon fits nicely alongside.
5-Ingredient Slow Cooker Anchovies
Servings: 4
Ingredients
2 cans anchovy fillets in oil, drained
1 can (28 ounces) crushed tomatoes
4 cloves garlic, thinly sliced
1/4 cup olive oil
12 ounces spaghetti
Directions
1. Add the drained anchovy fillets, crushed tomatoes, sliced garlic, and olive oil to the slow cooker. Stir gently just enough to distribute the garlic and nestle the anchovies into the sauce.
2. Cover and cook on low for 3 to 4 hours, until the anchovies have mostly dissolved and the sauce smells mellow, savory, and rich.
3. About 15 minutes before serving, cook the spaghetti in well-salted boiling water according to package directions until al dente. Reserve a little pasta water, then drain.
4. Toss the hot spaghetti with the slow cooker sauce, adding a splash of pasta water if needed to loosen and coat the noodles evenly. Serve right away.
Variations & Tips
Tomato balance: If your canned tomatoes are especially acidic, let the sauce cook the full 4 hours on low so the flavor rounds out more fully. Anchovies add salt and depth, so taste before thinking you need anything extra.
Add gentle heat: A pinch of red pepper flakes is an easy addition if you want a little warmth. Stir it in at the beginning so the spice softens into the sauce rather than sitting sharply on top.
Serve it differently: This sauce is also very good spooned over creamy polenta or piled onto thick toast for a small-plate supper. Because the anchovies dissolve into the sauce, the final dish tastes savory and complex rather than strongly fishy.
Pasta tip: Undercook the spaghetti by about a minute if you know you will toss it thoroughly with the hot sauce. That keeps the texture from going too soft and helps the noodles absorb flavor while staying pleasantly firm.
